2 Features Three individual stepper drive boards Suitable for NEMA17 to NEMA23 stepper motor Input voltage 20-60VDC MAX peak current 6.0Amp Extra smoothness and good high speed performance 8 selectable current and 8 selectable micro step resolution Interface to PC s parallel port and MACH3 Interface to CNC machine peripheral equipment like inverter, end limit Isolated 0-10V Note1 output for spindle speed control 4 isolated GP digital outputs for the spindle I/O or other equipment Built-in short circuit, over-current and over-voltage protection for each drive board Power and fault indicator for each drive board Charge pump indicator in the breakout board One switch to disable/enable the charge pump Built-in digital smoother of each drive board Descriptions Leadshine s MX3660 is 3-axis stepper drive which integrates 3 stepper drive boards and one break out board into one drive case. As the drive board adopts the latest DSP control technology, the driven motor can run with extra smoothness and lower heating. Each drive board has 8 currents and 8 micro step resolutions selected by a 6-bit DIP switch. A parallel break out board which provides 0-10V Note1 analog output, E-STOP input, 4 general purpose digital inputs and 4 general digital outputs has been built into the MX3660 so it nulls any additional equipment when connecting to PC s parallel port and controlling by Mach3. However, users can also take it as traditional stepper drives and control them by step/direction signals via the DB25 port. Applications Leadshine s MX3660 are specially designed for those applications which adopt PC and MACH3 or similar software as the control platform. However it can be used in various applications such as laser cutters, laser markers, high precision X-Y tables, labeling machines, CNC router, etc. Its unique features and compact size make the MX3660 an ideal choice for applications that require both low-speed smoothness and small mounting space. Note1: The actual analog output is V when the input is 10V.. 3/F, Block 2, Nanyou Tianan Industrial Park, Nanshan District Shenzhen, China Page 2/9
